* add deprecation warning for int ReactorBase::type() (to be changed after Cantera 2.5)
* introduce temporary std::string ReactorBase::typeStr() (to be renamed after Cantera 2.5)
* deprecate all functions using the old call and introduce associated temporary functions
Without these functions, it was impossible to use these classes
without leaking memory. Even with these functions, the memory is
released only when these functions are explicitly called, as
old-style Matlab classes have no notion of a destructor.
Fixes#252.
These changes make it unnecessary to copy header files around during
the build process, which tends to confuse IDEs and debuggers. The
headers which comprise Cantera's external C++ interface are now in
the 'include' directory.
All of the samples and demos are now in the 'samples' subdirectory.
